March 2, 1954 J. A. HOWARD FILTER FOR CIGARETTE HOLDERS Filed March 25,1950 Patented Mar. 2 1954 This inyention relates to a filter itortaigarette holder, the particular holder being more shown in myico-pend'mgapplicaticmifiled of even date herewith bearing Serial No. 151,932.

One ofthe objects of this invention to provide :a filter-whichamay theeasi y misented into a cigarette holder and yet will e'fiectivelyfilter-eerta-in contaminants icigamettesmoke which otherwise would enterthe month. t

Another object of this inventionzis to'pnovide & fitter which may heeasily inserted in the cigarette holder and withdrawn therefrom.

Figure 4 .is a section on line 4-4 of Eigure o1;

Figure 5 is an exploded View showing in perspective the various partswhich enter into the holder and filter.

In proceeding with this invention I provide a tubular cartridge whichmay be inserted into a holder and cover this cartridge with cork, andmount at one end of the cartridge a mouthpiece which is also coveredwith cork and which affords a means for holding the holder in positionwith the barrel of a cigarette holder.

With reference to the drawings, l designates the barrel portion of acigarette holder which is tapered at one end as at H and receives inthis end a cigarette l2 shown in dotted lines. This holder in is usuallyof metal although it may be made of non-metallic materials as desired. Athreaded surface is provided at the other end of the holder as at I3 forholding the filter within, and a band I4 is provided which may serve asan ornament on the outer surface of the holder and may be slid along theholder to various positions.

The filter comprises a. removable cartridge in the form of a metal tubeor shell l5 which forms a tubular chamber of the filter and is providedwith a resilient cork covering [6 over its outer I 5 Qlaims.

The shoulder extends out beyond the chamber portion of thefilter and a ferrule 21 may be, provided having an inwardly extendingflange 28 to engage the opposite side of said shoulder, while itsthreads 29 may engage the threads 13 for holding the filter within thetubular holder I0.

In order to keep the sack expanded so that air may pass therethrough, Ihave provided a resilient member designated generally 30 and whichcomprises a pair of arms 3| and 32 secured together by the arm 32 havinga tongue 33 bent over the surface of the arm 3| so as to bind the twoparts together. These attached ends of this resilient member may beinserted into the bore 22 by forcing the same into this bore so as tosupport the resilient member in position. These arms 3| and 32 are inthe form of resilient spring parts which flare outwardly due to theinherent set of the stock so that the ends 34 and 34' of this springmember will press against the sack adjacent the openings 26 so as tohold the sack expanded and the openings free for the passage of air andsmoke therethrough. However, these openings are of such size as to catchany solid particles which may otherwise pass into the sack.

In operation, when drawing in at the mouthpiece end of the filter, smokeand air from the cigarette will pass through the inlet openings l8 intothe chamber 35 and there solid particles will tend to settle out or becaught in the more restricted portions between the sack and the shell orabout the openings 26, while the smoke and air will pass through thesack and into the mouthpiece. As the contaminants of the smoke collect,the chamber 35 will gradually become filled with the contaminants andafter a certain length of use which may be determined by experience theshell I and its end wall (I may be removed and replaced or the sack 25may be removed, the sack and spring member cleaned and the sackreplaced.

The cork tip provides a good mouthpiece and for feminine use may becolored as desired.

Iclaim:

1. A smoking device comprising an outer tubular member open at each endthereof and externally threaded at one end portion and having a straightbore extending inwardly from the said threaded end thereof, a reducedbore extending inwardly from the other end thereof of a size to receivea cigarette therein, and a tapered relatively short bore extendingbetween said straight and reduced bore portions, a tubular shell open atone end and having an apertured wall at the other end providing achamber, said tubular shell being of a length substantially equal to thelength of said straight bore and received therein in sealing engagementwith the walls of said straight bore portion and with the apertured wallof said tubular shell abutting against the wall of the said tapered boreportion at the in tersection thereof with said straight bore portion, amouthpiece having an end portion thereof extending into said tubularshell and provided with an annular shoulder one side of which abutsagainst the open end of said tubular shell and the end of said tubularmember, threaded means abutting against the other side of said shoulderand engaging said externally threaded portion to detachably secure saidtubular shell and mouthpiece to said tubular member, and a sackextending into said chamber and frictionally attached to said mouthpieceat the end portion thereof within said tubular shell and providing asnug frictional engagement between said mouth piece and said tubularshell at the said reduced portion of said mouthpiece and adjacent wallof said shell, said sack having a. plurality of small openings thereinat the free end portion thereof whereby smoke drawn from the cigarettewill pass through said chamber and sack to be filtered as passingtherethrough.

2. A smoking device as in claim 1 further comprising a V-shapedresilient member secured at the apex of the V in the bore of the saidmouthpiece and extending into said sack to keep it expanded.

3. A smoking device as in claim 1 further comprising a resilientcompressible covering frictionally engaging said tubular shell and of asize when under slight compression to be snugly received within saidstraight bore.

4. A smoking device as in claim 1 wherein said threaded means forsecuring said mouthpiece and said tubular shell to said tubular membercomprises a ferrule threadingly engaging said tubular member and havinga flange extending into engagement with the other side of said shoulder.

5. A smoking device as in claim 1 in which the inner apertured wall ofsaid tubular shell is spaced from the reduced bore portion a distance toprovide a stop for engaging and limiting the distance the cigarette maybe inserted into said tubular member.
